Select the answer using the code given below:

1. A

   1 only

   Claims statement 1 alone is correct, but statement 3 is also correct as Lake Turkana is a UNESCO World Heritage Site and known as the Jade Sea, making this option incomplete.

2. B

   1 and 3 only

   1 and 3 only. Lake Turkana is indeed the largest permanent desert lake in the world and the world's largest desert lake overall. It is also a UNESCO World Heritage Site and famously called the 'Jade Sea' due to its striking turquoise waters.

3. C

   2 and 3 only

   Claims statements 2 and 3 are correct. Statement 2 is incorrect because Lake Turkana is located in the Kenyan Rift Valley, primarily in northern Kenya with a small portion extending into Ethiopia, not in South Sudan along the Sahara desert.

4. D

   1, 2 and 3

   Claims all three statements are correct. This is incorrect because statement 2 is factually false regarding the geographical location and country of the lake.

Summary. Official key is (b). Lake Turkana holds the title of the largest permanent desert lake and the world's largest desert lake, and is a recognized UNESCO World Heritage site dubbed the 'Jade Sea'. Statement 2 fails because the lake lies in Kenya and Ethiopia within the East African Rift system, far from South Sudan and the Sahara desert.
